Evidence / storm surfaces
How Marcus saw the hail — from two instruments
Each storm gets two readings: the radar signatures NEXRAD recorded as the cells passed overhead, and a modeled estimate of hail size in the air. They are independent surfaces, so a mismatch between them is expected — and worth reading.
Estimated size field Radar-estimated hail size over the swath. The model reports the biggest stone the storm could sustain in the air; what actually fell may have been smaller.
Only the radar-estimated size surface resolved for Oct 8, 2026 — this storm produced no NEXRAD point detections over Marcus, so there is one map to show, not two.
The storm in context
Where Oct 8, 2026 sits in Marcus's hail record.
This was Marcus's 11th recorded hail day, arriving 32 days after the Sep 6, 2026 storm. By severity it ranks 3rd of the 11 storms we have logged here. Radar put the day's largest stone over Marcus at 1.25" — radar-estimated size aloft.
The Oct 8, 2026 convective day was bigger than Marcus: the same system put hail over 86 other tracked cities, 76 of them in Iowa. Nearest: Paullina (6 miles northeast, up to 1"); Cleghorn (6 miles southeast, up to 0.75"); Remsen (8 miles west, up to 2").

Ground reports
What people on the ground reported
These are storm reports filed with the National Weather Service and released through the NOAA Storm Prediction Center — public-domain observations from spotters, the public, and NWS surveys. We quote each one exactly as filed.
The National Weather Service logged no spotter reports for this storm over Marcus. That absence is ordinary — filing a report takes a person on the spot who saw the hail and phoned it in. What stands as the record for this date is the radar above, which caught the storm regardless.
Damage-capable hail signal
What 1.25" hail means for Marcus roofs.
Quarter-size and larger hail can bruise asphalt mats, remove granules, and dent exposed soft metal. The mapped footprint identifies an inspection priority area — it does not identify which individual roofs, if any, sustained damage.

Roofing exposure
What this storm is worth to a roofer.
Potential roof exposure
$24M
Potential roof exposure — 2,010 homes × the ~$12,000 industry-average hail roof claim. Exposure, not confirmed damage.
- Illustrative jobs
- 10 jobs
- Illustrative work
- ~$150K
Close just 0.5% of the 2,010 homes in this footprint at the average $15,000 roof job. Illustrative math, not a projection — your results depend on your outreach and how the market responds.
Claim window
October 2028
Claims from this storm can typically be filed until around October 2028 — the window to reach these homeowners while it's still open. Deadlines vary by policy and state.
Names and phones for every home in the footprint: at most $422 on top of the $150 plan.
